Grid Metals Intersects High-Grade Cesium at the Falcon West Cesium
Project including 14.0% Cs2O over 3.01m
November 20, 2025 TORONTO -- Grid Metals Corp. (TSXV: GRDM; OTCQB: MSMGF) ("Grid" or
the "Company") is pleased to announce the first five assays from its 2025 cesium-focused drill
program at the 100% -owned Falcon West Cesium property (the "Property") . The Property is
located approximately 110 km east of Winnipeg , Manitoba. The drill target at Falcon West is
pollucite-hosted cesium mineralization within the Lucy South lithium -cesium-tantalum (“LCT”)
pegmatite. Lucy South is a highly fractionated, shallow, and flat-lying pegmatite which is located
approximately 500 metres off the Trans-Canada highway. Initial 2025 drilling has intersected the
Lucy South pegmatite including a strongly fractionated core zone carrying high grades of cesium,
lithium and rubidium.
Highlights from the first five drill holes include:
• 1.73 metres with 14.0% Cs 2O, 1.71% Li 2O and 0.36% Rb 2O (LU25-01; from 27.1 metres)
including 0.42 metres with 27.4% Cs2O
• 3.01 metres with 14.0% Cs2O and 0.50% Rb2O (LU25-03; from 31.5 metres) including 0.61
metres with 24.2% Cs2O and 0.50 metres with 24.7% Cs2O
• 2.90 metres with 9.6 % Cs2O and 1.85% Li2O (LU25-04; from 25.8 metres) including 0.85
metres with 19.6% Cs2O
The Company is in the process of completing approximately 70 drill holes, focused on delineating
the initial near-surface strike and extent of the Lucy South pegmatite and the distribution of
cesium within it. The current drill program is the first concerted effort to define the potential for
a cesium resource at the Property . The Company is pleased to note that the cesium
mineralization in the first five drill holes appears to be primarily associated with the mineral
pollucite, the preferred mineral for cesium chemical processing.
Dr. Dave Peck, P. Geo., Grid’s Vice President of Exploration, stated "Our Falcon West cesium drill
program is off to a great start with hole LUC25-03 returning the highest cesium grade-thickness
intercept ever recorded at the Property and one of the highest grade-thickness cesium intercepts
reported in recent years, globally. Cesium grades north of 20% in drill core are exceptionally rare,
marking the Lucy South pegmatite and the Falcon West property as a notable geological target.”
Robin Dunbar, CEO of Grid Metals, commented, “Cesium is one of the rarest and most sought -
after critical metals with a growing number of strategic applications. In the last several months ,
it has been designated a critical metal by both the U.S. and Canadian governments. The cesium
market is facing a global shortfall of feedstock to supply a growing number of applications
including defense applications and next-generation solar panels. We are off to a positive start in
our efforts to demonstrate that Falcon West has the potential to develop into a global ly
significant cesium project to support a North American focused cesium supply chain.”
Drill Results Discussion
The current area of exploration interest is the near-surface portion of the Lucy South pegmatite
where several recent exploration campaigns identified high cesium values. The initial area of
interest is a n approximate 150x40 m area where the Lucy South pegmatite is within ~35 m of
surface. In th is initial phase , a substantial portion of the target area will be drill ed at closely
spaced centres.
To date, drilling has identified a distinct zonation pattern of mineralization within the Lucy South
pegmatite. Zonation consists of a wall zone on the margins of the pegmatite with variably
developed internal subzones enriched in cesium (pollucite +/- biotite), lithium (spodumene +/ -
lepidolite), rubidium ( feldspar +/ - biotite) and tantalum (presumed to be associated with
columbo-tantalite). The discrete nature of the pegmatite and the distinctive mineral assemblage
provides a well-defined exploration target for the ongoing and future drill programs.

holes completed in this area.
Figure 2: Drill-defined locations of the Lucy South and Artdon LCT pegmatites overlain on a total
field magnetic image based on the Company’ s fall 2024 fixed -wing magnetic and radiometric
survey. The d otted white line identifies the current regional exploration target that follows an
extensive magnetic low anomaly that hosts both the Artdon and Lucy South pegmatites. The
latter two areas may be part of a single LCT pegmatite – but are separated by several hundred
metres where no drilling has yet occurred.
Next Steps
As discussed, t he Company is planning to complete approximately 70 drill holes by the end of
2025 with all holes targeting Lucy South within approximately 35 m of surface. Based on the
success of the current program, a follow-up program would likely commence in January 2026.

Quality Assurance and Quality Control
The Company’s ongoing exploration program at the Falcon West lithium property is being
supervised by Dave Peck, P.Geo. Grid Metals applies best practice quality assurance and quality
control ("QAQC") protocols on all of it’s exploration programs. For the current program all core
was logged and sampled at the Company’s core facility located on its Makwa nickel property.
Generally, 1.0 metre sample lengths were used. Samples were bagged and tagged and then
transported by secure carrier to the Activation Laboratories facility in Ancaster, Ontario for
sample preparation and analysis for lithium, cesium, rubidium, tantalum and selected major and
trace element abundances using a sodium peroxide fusion total digestion method followed by
ICP-OES and ICP-MS analysis. The Company is using two rare metal certified reference materials
("CRMs") and an analytical blank for the program to monitor analytical accuracy and check for
cross contamination between samples. The blank and CRM results for the reported interval s
were determined to fall within the accepted range of deviation from the certified values.
Dr. Dave Peck, P.Geo., the Company’s Vice President, Exploration, has reviewed and approved
